the smoke will be greatly reduced to produce.

a cool smoke. Many forms of pipes have heretofore been produced with these objects in view, but the devices used have been enclosed in non-conductive walls with the result that after a number of smokes the evaporated oil soon collects on the separating means and contaminates the saliva which is sooner or later accidentally drawn back into the mouth of the user of the pipe. This is because the devices are confined within the area and enclosed within the walls of the pipe. By my invention, the smoke is cooled near the Vbowl end of the pipe and before its entrance into the bit end of the pipe. The cooling devices heretofore used being located within the confines of the walls of the pipe, which are heat insulated, prevents cooling of the smoke after the first few puffs, thatis, the cooling means soon becomes as hot as the smoke itself. The cooling'means of my invention is not confined within the walls of the pipe, but constitutes a continuation of the walls and is thus directly subject to the cooling temperature of the atmosphere and, being formed of an oil conductive material, it maintains a cool smoke and alsomaintains the saliva in the bit end of the pipe and prevents it from entering the bowl where it ordinarily separates the tobacco at the bottom of the bowl. L The invention may be contained in pipes that vary Vin their details and, to illustrate 4o a practical application of the invention, I have selected a pipe containing the invention as an example of such structures andshall describe it hereinafter. The pipe selected, is shown in the accompanying drawings.

Fig. l is al perspective view of the pi'pe.

Fig.. 2 illustrates a longitudinal section through the pipe.

In the form of constructionk shown in the drawings, the usual pipe having a'bowl 1 and a bit 2, are completely-separated and interconnected by a sinuous or invertedv U-shaped metallic member 3. The member 3 is, preferably, tubular in form and is inv sertedV inthe end of the stem 4 of the bowl l and in the end of the bit 2. Preferably, the

which is attractive in appearance and is also oil heat conductive. The ends of the inverted U-shaped member 3 extend, preferably, in

axial alignment withv4 the bit 2 and the stem;`

tobacco andother volatile parts are condensed.

or discharged upon the surface of one leg of the U formed by the passage-way 6 within the U-shaped tube that extends upwardly tubular member 3 is formed of aluminum to,A

from the passage-ways of the stem of the bowl and the bit. 'Inasmuch as ther tubular memc ber 3 has its surfaces located on, or quite entirely in contact with the exterior atmosphere, the tubular member 3 is kmaintained substantially at the temperature of the at* mosphere and although the pipe may be continuously used, yet the temperature of the tubular member 3 will rise but slightly. This keeps the smoke .cool as it is drawn into the mouth of the user of the pipe. Preferably, l the wall of the tubular member 3 is thin which aids in conducting theheat from the surface v within the tubular member 3 Vto the surface f Y 'exterior to the member 3. Also, the saliva.

will be kept in the bit 2 by the passage-way 6 whichY extends laterally with respect to the axis of the bit 2 and also the axis of the stem 4 where the ends of the tubular member connect with the bit 2 on the one end and thepstem 4 of the bowl on the other.

I claim: A pipe, having a, bit and a bowl, an inverted UK-shaped tubular member having progres sively curved portions throughout its length, the ends of the U-shaped memberlocated substantially in alignment with each other and extending in opposite directions, one end connected to the bowl and the other end connected to the bit. g

In Witness whereof I have hereunto signed my name to this specification.
